Ben Cohen's ex-wife Abby is reportedly "devastated" that Kristina Rihanoff is expecting a baby with the rugby star

Abby Cohen is reportedly fuming that her former husband didn't tell her about the baby news before the 'Strictly Come Dancing' star revealed all during her stint on 'Celebrity Big Brother'.

A friend told The Sun newspaper: "Abby is absolutely devastated. The first she knew of it was when people began ringing her. How could he be so cruel as to let her find out about the pregnancy this way? It was insensitive and hurtful.

"The fact Ben didn't even have the decency to tell Abby before she revealed it to her housemates on the show cut her to the quick. She sent him a flurry of angry text messages asking for an explanation."

Meanwhile, Abby - who has seven-year-old twin daughters Harriette and Isabelle with the ex-rugby star - has admitted the news is a "shock to us all".

She said: "This news has come as a shock to us all. Please respect mine and my children's privacy at this time."

Ben met Kristina when they were partnered together on the BBC One show in 2013.
